Radon levels in St. Louis are a real concern because the area sits on a mix of soil and bedrock that can release this radioactive gas. Many older homes in the city and suburbs have basements or crawlspaces where radon can accumulate. Local health agencies recommend testing every few years, especially after renovations. I know several families who found elevated levels and had to install mitigation systems. It's worth the simple test kit cost for peace of mind.
